DRILLING AND NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 791,2.87, dated Hay 30, 1905.

Application tiled November 14, 1903. Serial lo. 181,214.

To all 10h-om it may concern.-

Be it known that I, JULIAN L. Pimm-Ns, a citizen of the United States, residingin West Springfield, in the county of Hampden and State of Massachusetts. have invented certain new and useful Improvements in Drilling and Nailing Machines of which the following is a specification.

This invention relates to a machine for drilling and nailing copper, zinc-etchings, and electrotype-plates to wooden blocks or metal f bases- In the machines heretofore in use the nail is driven through the copper, zinc, or electrotype plate. This causes the surface adjacent to the nail to be slightly deected. 'hen great care is not exercised in driving I the nail, it will cause depressed places to be formed in the cut. thereby spoiling the plate. The object of my machine is toovercome this defect by first drilling the hole through the plate and then driving the nail through the t hole into the wooden or metal block or blocks; and for this purpose the invention consists of a combined drilling and nailing machine for use in newspaper and other printing oiiic, which will be fully described hereinafter and finally pointed out in the claims. f

In the accompanying drawings, Figure 1 is a side elevation of my improved drilling and nailing machine. F ig. 2 shows the machine in front elevation. Fig. 3 shows a similar view of the upper portion of the machine drawn on a larger scale. Fig. 4 is a vertical section on line 4 4, Fig. 3. Fig. 5 shows in perspective a portion of the nail-feeding device. Fig. 6 is a horizontal section on line 66, Fig. 3. Figs. 'a'and 8 arediagrams showing the relative succeive positions of the crank-pin and movable carrier. Figs. 9 and 10 are details showing the return positions of the nail-feed-operating cam. Figs. 11 and 12 show the nail-feed tube and separating-cam in two positions. Fig. 13 shows the separating-cam block in section, and Fig. 14 is asectional view of the nailholding block.

Similar letters and numerals of reference Referring now to the drawings, 12 is a stand of any preferred form, having a table 13 mounted thereon and a supporting-standard 14 at the top of the stand. On the overhanging end of the standard 14 slides a carrier consisting of a plate 15, with anged portions 16 and 17 that overhang the upper and lower edges 1S and 19 of the standard, thereby permitting the carrier to slide horizontally` on the standard.

The standard 14 has journaled therein a horizontal main shaft 20, having at its outer end a crank-disk 21, carrying a crank-pin 22, as best shown in Figs. 1 and 6. The shaft 20 is rotated intermittently by any suitable means, preferably from a double driving-puh ley 23. that is constantly driven and from which motion is transmitted to the shaft 20 by a clutch arrangement controlled from the foot-lever 24 through the medium of theA s connecting-rod 'Z5 in any of the well-known ways.

The slidable carrier-plate l5 is reciprocated from the crank-disk 2l by the crank-pin 22 engaging the walls of an irregular slot 26 in the plate 15. This slot is of a vertical length equal to the throw of the crank-pin. Hence one revolution of the shaft 20 will cause one complete reciprocation of the rrier 15 and by an irregular motion that will be described hereinafter.

The carrier-plate 15 has supported thereon a drillspindle 30, rotatable in a journal 3l at the upper part of the carrier and in a journal 32 at the lower portion of the carrier. The drill-spindle is rotated by a belt 33 engaging its pulley 34, which belt passes around guidepulleys 35 and thence down and engages a pulley 36 on the stand 19.. The pulley 36 may be driven from a part of the main pulley 23 by suitable belt. From Fig. l it will be observed that the carrier may be reciprocated within certain limits without disturbing the action of the belt 33 on the pulley Sit-that is, the spindle 30 will be continually rotated in the several positions of the carrier. The pulley 34 is not rigidly secured to the spindle 30, but is connected therewith by a spline 3T on the pulley engaging a groove 38 in the spindle 30, thereby permitting the spindle to be vertically reciprocated while' rotating.

The spindle 30 is actuated or vertically reciprocated by a double bell-crank il), pivoted on a pin 41. The arm 42 of the bell-crank extends between tixed collars 43 and 44 on the spindle 30, while the arm 45 of the bell-crank is retained in the path of movement of the l crank-pin 22 by a spring 46, secured to the Y,

carrier-plate and to the third arm 4i' of the bell-crank. Thus it will beseen that the cran kpin will strike the arm 45 and rock the bellcran k,and thus reciprocate the drill-spi ndle 30.

The nails are placed in any quantity in a box 50. pivoted at its lower end to a guidetube 51, the latter having a longitudinal slot 52 at the top, while the box 50, preferably tubular, hasa slot in its bottom portion in alinement with the slotted portion of the tube 51. The box 50 is oscillated by a link 53, connecting the box with acrank 54, the latter- E rotating on a short shaft 55, that is rotated by suitable gears from the main shaft 20.

'hen the nails reach the lower end of the tube 51, they are received by a forked extension 56 of the tube 51, that is arranged horizontally. The end nail isengaged by theside l face of a tubular separating block 57, that z oscillates in a journal-box 58, carried by a bracket 59, the latter being secured to the E standard 1L The block 5T basa bore 60 leadf ing to a hook portion 61 at the top, by which when the block is oscillated the end nail will be fed into and engaged by the opening inside A;

the hook. and thus carried down through the bore of the block.

From Figs. 5 and 1l, which show the nailblock 57 in its normal position, it will be ob- E served that the end nail is resting minst an i abutment-face 6:2 of the block 57, which in conjunction with the sides of the extension 56 prevent the nail from further clockwise it will be Seen thehook 61 will pass between the said end nail and the adjacent nail just below the exbore 6I) of the block and fall therethrough by gravity. It will beseen, further, that the next nail in the strip 56 is prevented from advancing by engaging the outer face of the hook l 61, and upon the block being rocked back to its former position as Soon as this succeedingnailisreleased from thesaid outerface of the hook it will advance but a short distance until it strikes the said abutment-face 62, which-will arrest this nail and also the sucon until the next oscillation of the 1 block. 'Bins at each complete oscillation back and forth of the block one nail will be Selected and fed into and the block. In orderto oscillate the slid block 5T at the proper time in the revolution of the crank-disk 21, I provide an arm 63, secured to the lower portion of the block 5T, which arm advancing and the other nails from feeding downward; but upon the block 5T being slightly oscillated from Fig. 12 that 5 carries a pin 64. A bar 65 is supported on y the upper overhanging part 1T of the carrierplate and has a cam-lug 66 arranged to strike the said pin 64 upon the carrier-plate being reciprocated, and thereby rock the block 5T from its normal position, as shownin Fig. 11, i in which position it is vieldingly retained by a plate-spring 6i", secured to the bracket 59, and engaging a pin 90, that projects through a slot in the journal-box 58. This bar 65 is so disposed on the carrier that its cam will engage said pin 64 at the latter part of the movement of the carrier to the left, for a purpose hereinafter set forth; but means are also provided whereby the bar 65 is given an endwise movement` thereby to amplify the movement of the block 5T by the cam. To this end the lower bent portion of the bar 65 is 5 dovetailed, which portion slidably engages a correspondingly-shaped channel in the top 17 of the carrier-plate. A bar 68 is connected with the arm 4T of the bell-crank by a link 69 and is guided for endwise movement in a box T0 on the plate l5. An irregular extension 71 of the bar 68 has a diagonal slot T2 therein, whose walls engage a bolt 73, secured to the said bar 65. Thus it will be seen that the rocking of the bell-crank 40 will through the bar 68 and the bolt T3 cause a reciprocation horizontally of the bar 65, and thereby oscillate the block 57 when its pin 64: is within operative position with relation to the cam 66. It may be here stated that the bar 68 may be dispensed with and the bar65 rigidly secured on the plate l' by so designing and arranging thecam 66with relationtotbe block 57 and its operating-pin that the movement of the carrier will produce suicient oscillation of the block 57.

On the carrier-plate 15 is secured a guidetube 74, whose upper Haring end is opposite the bore in the block 5i' when the carrier is at v the limit of its left-hand position, and it is at g' this stage of the operation that the nail-feeding device above described is operated to feed ,fa nail through the bore in the block. The nail passes downward through the guide-tube T4 and is received by a holder comprising two blocks 75 and T6, that are normally retained in engagement by means of a spring 7.7, that is interposed between an inner annular liange T8 on the block 76 and a nut T9. i turning on a screw-bolt 80, secured to the block 75. Guide-pins 81, secured to the block T5, slide in sockets 82 in the block T6, thereL by producing a prgper movement of the blocks when separated. The opposing faces of the blocks each contain a groove 83, extending l vertically the length of the block, and an inclined groove 84, leading into the groove 83,. through the bore of the said grooves registering in the blocks. thereb providing a bore for the reception of A the nail from the tube '7L The lower end portion of the channel 83 in the block is coni stricted or tapering, as shown at 85, that the IIO head of the nail will be engaged at this part and arrested in its passage through the block until by suitable means the blocks are separated against the force of said spring80. thereby so enlarging the bore that the nail may pass out. The nail that is retained in the said block is forced out of the same and into the aperture made by the said drill at the proper A stage in the operation of the complete device by a reciprocating hammer or driver. The latter consists of a rod 86, secured in a bore in an arm S7, projecting forward from a reciprocating plate 88, that slides in a channel in the rear face of the carrier-plate 15, which plate is reciprocated by reason of the crankf pin 2i). engaging the walls of a slot 89 in the plate. The lower end of the nail-driving rod 86 is made converging and of a size to engage the converging bore of the block at the proper time when its lower end shall have reached the head of a nail retained at said portion of the block. Thereupon the further downward l movement of thedriver will separate the movable members of the block, permitting the nail to pam downward, and at the same time the driver will follow the nail and force it into a drilled block on the support of the machine.

The operation of th'.- several parts above described is as follows: 'ith the crank-disk at rest and the cranl;pl pin to the right, as shown in Fig. 3, it will be seen that the nail-driver is in an intermediate position and that it will be raised upon the crank-pin moving upward to the limit of its movement and will be depressed upon the crank-pin moving downward from said position to its lcivermost position. Now suppose the crank-disk to be moved clockwise through ninety degrees, bringing the pin to its uppermost position. It will be evident from Fig. 3 that the nail-driver will move upward, while the bell-crank will be oscillated once by the engagement of the crank-piu with the arm 45. Duringthis movementol' the crank-pin it will beseen from F ig.' A that the portiol. of the irregular slot 26 i through which the pin moves is substantially l concentric with the crank-disk. Hence the crank-pin will strike no abutment-face that would cause the carrier to be moved-that is, the carrier is stationary with respect to a block on the work-support. This rocking of the bell-crank will cause the continuously-rotating drill-spindle 34) to be moved downward its limit and then return, which by the proper adjustment of the block on the support will cause a hole to be drilled to the proper depth through the electrotype and into the supporting-block. The next partial movement of the crank-disk will advance the crank-pin from the position of a, Fig. 8, to the position of b and by reason of the pin striking a portion l of the slot not concentric with its movement will move the carrier from its position as inl dited in Fig. T to the position in which showninrig. Now tha-.throw ofthecmkl pin and the contour of the slot 26 are so arranged that the said movement of the carrier will be for a distance equal to the distance apart of the axis of the drill-spindle 30 and the axis of the bore 83 in the nail-retaining block. Hence. the electrotype and block being stationary on their support, the bore 83 of the nail-holder will be brought to the exact position just occupied by the drill, and it is now in order to feed a nail into the hole made b v the drill in the block and drive it home. The further advancement of the crank disk and pin, that would bring the crank-pin from the position of b to that of c, Fig. 8, will not move the carrier, because the portion of the irregular slot 26 is now concentric with the path of movement of the crank-pin; but when the crank-pin pases from the position of a to that of it will be seen that its engagement with the slotted portion of the plate carrying the nail-drive'i 86 will cause the driver to descend a short distance, and the further movement from l: to e will cause the driver to engage the nail in the retainer and also to open the retainer-block, thereby forcing the nail into the now registering hole in the electroi type and block and driving it home into the same. The fourth and last step in the revolntion of the crank disk and pin moving the pin from the position of f: to that of d will cause the pin to so engage the wall of the slot as to move the carrier back to its former position in which shown in Figs. Sand T. This last movement will also have the etect of withdrawing the driver-rod for half of its distance of movement vertically; but it will also be evident that during this last movement the cam 66 will strike the pin 64, connected with the nail-feeding device, and operate the latter to feed a nail through the guide-tube T4 down into the receiving-block, where it will be retained until the hammer next descends, as above described. It may be further stated that in the tirst step of the movement the arm 4T of the bell-crank will, through the bar 68. move the bar65 and give additional movement to the nail-feeding block 5T should the former movement of the same not have been suticient to cause a nail to be fed; but, as hereinbefore stated, this last operation is not necessary, provided the cam 66 is so constructed and arranged as to sutiiciently operate the oscillating block 57.

From the above it will be apparent that during two steps of the operation, not consecutive, the carrier is moved and that during the alternating steps the drill and the nail-driver are operated respectively. It will further be apparent that the drill is moved downward and then withdrawnthat is, given a full reciprocation during the tirst step-so that the drill will be entirely out of the block before the second step shall have caused the carrier to move the drill bodily with respect to the block, and also that the nail-driving rod does head of the nail will be engaged at this part 'and arrested in its passage through the block until by suitable means the blocks are separated against the force of said spring 80, thereby so enlarging the bore that the nail may pass out, The nail that is retained in the said block is forced out of the saine and into the aperture` made by the said drill at the proper' stage in the operation of the complete device by a reciprocating lhammer or driver. 'The latter consists of 'a rod 86, secured in a bore in an arm 87., projecting forward from a reciproeating plate 88, that slides in a channell in the rear face of the carrier-plate 15, which plate isrecprocated by reason o f' the cranlr able members .of the block, permitting the nail to pass downward, and at the saine time the d river will follow the nail and force it into a drilled block on the support of the machine.

The operation ofthe several parts above de- 'scrihed is as follows:A vWith the A'crank-disk at rest and the crank-pin to the right, as shown in Fig. 3, it will be seen that the nail-driver is in an intermediate position and that it will be raised upon the crank-pin' movingupward to the limit of its movement'and will be depressed upon the crank-pin moving downward from said positionl to its lowermost psition. Now suppose the-crank-disl: to be moved clockwise through ninety degrees,

bringing the pin to its uppermost position, lt will be evident from Fig. 3 that the nail-d river will move upward, while the bell-crank will' be oscillated once by the engagement of the crank-pin with the armi. During this moveinentol the crank-pin it will be'seen from Fig.7 that vthe portion of the irregular slot 26 through which the pin moves is substantially concentric with the crankdis'ln Hence the crank-pin will strike no abutmentface that would canse the carrier to be moved-that is, the carrier is stationary with respect to a block on the work-support This rocking of the bell-crank will cause the continuously-rotating drill-spindleSO to be moved downward its limit and then return, which by the proper adjustmentof the block on the support will cause a hole to be drilled to the proper depth through the electi'otype and into the supporting-block. The next partial'movement of the crank-disk will advance the crank-pin from the position of a, Fig. 8, to the position of b and by reason oi' thepin striking a portion of the slot not concentric with its movement will move the carrier from its position as indicated in Fig. 'l' to the position in which shown in Fig. 8. Now this throw of the crankpin and the contour ol the slot 26 are so arranged that the said movement of the carrier will be for a distance equal to the distance vapart of the axis of the drill-spindle 30 and the axis of the bore 83 in the nail-retaining block. Hence, the electrotype and block being stationary on their support, the bore 83 of the nail-holder will be brought to the exact position just occupied by the drill, and it is now in orderv to feed a nail into the hole made by the drill in the block and drive it home.

and pin, that would bring the crank-pin from the position of 5 to that of c, Fig. 8, will not move the carrier, because the portion of the `irregular slot 26 is now concentric with the path of movement of the crank-pin; but when the crank-pin passes from the position of a to that of it will be seen that its engagement with the slotted portion of the plate carrying the nail-driver 86 will canse the drivel' to descend a short distance, and the further movement from L to c will cause the driver to en gage the nail in the retainer and also to open the retainer-block, thereby forcing the nail into the now registering hole in the electrotype and block and driving it home into the saine. "lhe fourth and last step inl the revolution of the crank disk and pin moving the pin from the position of a to that of Z will cause the pin to so engage the wall of the slot as to move the carrier back to its former -position in which shown in Figs. 3 and 7. This last movement will also have the effect ot' withdrawing the driver-rod for halt` of its distance of movement vertically; but it will also "be evident that during this last movement the cam 66 will strike the pin 64, connected with 'the nail-feeding device, and operate the latter to feed a nail through the guide-tube 74 down into the receiving-block, where it will he retained until the hammer next descends, as above described. It may heA further stated that in the lirststep of the movement the arm 47 of the bell-crank will, through the har 68` move the bar and give additional movement to the nail-feeding block 57 should the former movement of thc same not have been suliceut to cause a nail to he fed; but, as hereinhet'ore stated` this last operation is not necessary, provided the cam 66 is so constructed and arranged as to su'lliciently operate the oscillating block 57.

From the above it will be apparent that during two steps of thcopcration, notconsecutive, the carrier is moved and that during the alternating steps the drill and the nail-driver are operated respectively. It will further be apparent that the drill is moi-'ed downward and then withdrawn-:that is, given a full reciprocation during the first stepmso that the drill will be entirely out of the block before the second step shall have caused the carrier to move the drill bodily with respect to the block, and also that the nail-driving rod does VThe further advancement of the crank disk .not enter to any appreciabledi'stanoe into the,
